Questions & Answers

Question:
Hi! How do I remove stays of this backpack?
Answer:
We recommend reading this page https://www.decathlon.com/blogs/sports-advice/how-to-care-for-your-backpacking-bag for complete details.
Question:
Is the fit - the suspension - adjustable? I'm 6-2
Answer:
We're happy to inform you that the torso length of the backpack is indeed adjustable to accommodate different body sizes, including yours at 6'2". To ensure a comfortable fit, it's essential to measure your torso length accurately. This measurement is the distance between your 7th vertebra (the prominent bone at the base of your neck) and your ilium (the top of your hip bones). Our backpack's adjustable torso length ranges from a minimum of 39 cm (15 inches) to a maximum of 51 cm (20 inches). Additionally, the waistband of the backpack is also adjustable to provide a snug fit around your waist. The waistband adjustment ranges from a minimum of 79 cm (31 inches) to a maximum of 136 cm (54 inches). Furthermore, the back panel of the backpack is adjustable with a release strap, making it easy and quick to customize the fit according to your preferences and body size. For the most comfortable and personalized fit, we recommend measuring your torso length and waist size using the provided guidelines before making your selection.
Question:
Is this backpack waterproof? Thanks
Answer:
The backpack includes a raincover stored in the bottom pocket, providing protection from rain.

Product Customer Reviews
At first glance it doesn't seem very big and quickly fills up but there is always a bit of space! Very good for bivouacs or backpacking holidays!
This piece managed to bring together the best and most useful features of the best and most renowned pilgrimage backpacks. Excellent value for money, designed by those who use it for those who use it.
backpack that meets expectations, used on many outings it has never disappointed me
I was looking for a spacious, lightweight, and breathable backpack.
Super practical backpack with lots of pockets and storage. Very comfortable adjustable carry. Can be used as a cabin bag with a little effort!
Very roomy backpack. Many compartments/pockets can pack a lot of different things that are useful during hikes. Very high comfort of wearing even a few hours on the back does not tire or cause pain.
very good backpack has a lot of space and many necessary pockets
Very comfortable and practical, holds a lot of stuff and the layout is great, looks great too
I have had several backpacks until I found this design, comfort, how it adjusts to the back and gives stability. I have the women's one and this one is for my husband. I definitely recommend it. Thank you 🙂
This is my third backpack and I can safely say that third time's a charm! The first one I had from a competing company was ok, but something didn't suit me, so I exchanged it for a simple model from Decathlon. It was also ok, but I wasn't entirely satisfied. Until I matured to decide to buy this model and... it's amazing in every way! The number and access to pockets, capacity, appearance, durability. There are no weak points, for me it's amazing! You won't buy anything better at this price, and if you come across a promotion, there's no point in even thinking about it! I recommend it!!!
I recommend it even for 2-week trips. I packed it for a 2-week trip to warm countries - it passed the test with flying colors. I appreciate the belt on the hips that relieves the shoulders, with the weight of the backpack being about 13 kg. When I traveled frequently by various means of transport, I found the rain cover useful, which, when put on the backpack and taped, protected the backpack perfectly. Overall, I highly recommend it, you can really fit a lot in the compartments.
Comfortable practice Perfect for a long hike and for roaming hikes.. ++++
The bag worked really well for me. I immediately packed it to the brim the first time I used it. It was very comfortable to use. It was easy to take out my packages/things.
High-performance backpack suitable for hiking with many very practical pockets. The little extra, the integrated rain cape.
renewal of my hiking bag, light, well compartmentalized, quality, to be seen with more use

How to pack a backpack?
Put your bedding at the bottom. Put heavy gear (tent, camp stove, food) near your back. Store your clothing around it. A groundsheet or tent can be placed under the flap or under the bag if there isn't room inside. Keep your waterproof jacket and fleece to hand. Place small items for daily use (sun cream, map, glasses etc.) in the pockets. The water bladder can be placed in the compartment provided down the back.
How to use the multi-use straps?
The new range of MT500 AIR and MT900 UL bags has two straps with open aluminum buckles (on the lower part of the bag). These straps let you hook on a tent or mattress under the bag or on the barrel. If not in use, these straps can be stored (by pushing them inside) in the hidden pocket intended for this or detached and used elsewhere with the lark's head knot buckle.
